String works in Python

a = 'String a'
b = "String b"
c = '''String c'''
d = """String a"""
e = 'Love\'it'  # to preserve quotes inside string - use back slash
f = "Love\'it"  # or use different quotes
g = '''multi
line string'''  # use triple quotes for multi line string    
h = "big\ttab"  # use special symbols with bacl slash
i = r"big\ttab" # raw input - back slahs will be ignored

print('abc'+'def') # abcdef
a='abc'
b='def'
print(a*3)         # abcabcabc
print(a*2.5)       # TypeError
print(a*b)         # TypeError
print(a + 34)      # TypeError

print("abc" in "abcdefghabcdefgh")    # True
print("abd" in "abcdefghabcdefgh")    # False
print("abcdabcd".find("bcd"))         # 1 (or -1 if not found)
print("abcdabcd".rfind("bcd"))        # 5 (or -1 if not found)
print(str.find.__doc__)               # Documaentation about find
print("abcdabcd".find("bcd",3))       # 5 (use search from position 3)
print("abcdabcd"[1:].find("bcd"))     # 0!!! - search is performed within slice!!!
print("abcdabcd".index("bcd"))        # 1 - works as find, but (ValueError - if not found)
S = "AB_CD_EF_GH.jpg"
print(S.startswith("AB_"))            # True; can use tuple as parameter
print(S.endswith(".jpg"))             # True; can use tuple as parameter
print("abcdefghabcdefgh".count("abc"))# 2 - not interlapping fragments!!!!
print("ababa".count("aba"))           # 1 !!! - not interlapping fragments!!!!

S="This is a Text, this text is nice"
print(S.lower()) # this is a text, this text is nice

print(s.rstrip("&_"))        #_&__1, 2, 3
print(s.lstrip("&_"))        # 1, 2, 3__&_&_&
print(s.strip("&_"))         # 1, 2, 3

print(" ".join(L))           # a b c
print(", ".join(L))          # a, b, c

template = "Move {} from {}"

x=1.239565432
print("{:.3}".format(x)) # 1.24!!! - this is proper rounding
